Brotherhood of NOD - Vehicles  
Here is the complete list of GDI vehicles in Tiberian sun with descriptions and pictures:  
Picture   Description
  In my oppinion this is the most impotrant vehicle in the game. Because without money you can do nothing. It's recommended to have at least 2 harvesters per refinery.
  This is the most effective NOD vehicle. It has very long range and does a lot of dammage. Great for base deffence but excellent for attack but it moves very slow and must deploy. Protect it against air attacks
  Great for sneak attacks on enemy base. Load it with cyborg commando and four engineers and go into enemy base. Use one more with some units as decoy first.
  This vehicle isn't very usefull. I don't use it at all.
  Excelent for scouting and great for attacks on enemy harvesters and voulnerable units. Use it in groups of 4 to 6.
  Excellent against infantry units. Great for deffence against engineers.
  Use this vehicle to expand your base.
  Detects cloaked and underground units.
  Repairs your vehicles.
  This vehicle is usefull for sneak attacks on enemy base and great for scouting. It must decloak when it fires (kinda like Klingon Bird of Prey).
  Good for defending your base. It can deploy to make some sort of turret. Then it is much harder to kill.
   
    Air Units
  This unit is based on alien technology. Great for attacks on enemy units and structures. Does a lot of dammage but it is best used in groups of 3 or 4 units.
  Great against infantry but not much use against anything else.
